ADJUSTABLE TAlLlNGS-BOARD FOR THRESHERS AND SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 650,811, dated my 29,1900.

Application filed October 26, 1899. Serial No. 734, 901. (No model.)

To all whom, it may concern.-

Be it known that 1, WILLIAM GINGRICH, a citizen of the'United States,residing atStiles,

in the county of Davis and State'of Iowa, haveinvented a new and usefulAdjustable Tail-- ings-Board for Grain-Threshers and Separators, ofwhich the following is a specification.

My object is to provide means for adjusting the tailings-board of ariddle in a grain thresher and separator while the machine is inoperation. I-Ieretofore it has been necessary to stop the work in orderto adjust the board as required to prevent grain from being blown outover the board. The condition and weight of grains vary, and when it isdiscovered that the air-blast carries light grains out over thetailings-board with chaif such loss of grain can be prevented byadjusting the position of the tailings-board relative to the frame thatcarries the screens. provided means for changing the angle of thetailings-board and also for raising and lowering it; and my inventionconsists in thecpnstruction, arrangement, and combination of parts, ashereinafter set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view showingmy invention applied to the rear end portion of a frame adapted to carryscreens as required in practical use in a thresher and separator. Fig. 2is an enlarged perspective view of one of the metal board-bearersadapted to be adjustably connected with the frame as required forsupporting the tailings-board 'at different angles and differentelevations at difierent times. Fig. 3 is an enlarged perspective view ofone of the metal end pieces having an integral rack adapted to be fixedt0 the end of a tailings-board and combined with metal board-bearers andthe frame of a riddle as required to raise and lower the board while themachine is in operation.

The letters A and A designate the parallel wooden sides of the frame ofa riddle-carrier.

B and B are mating metal bearers adapted to be adj ustably connectedwith the ends of the frame to support a tailings-board. Each has avertical groove c, an integralcurved and slotted arm 11, and aperforatedlug f and is connected with the outside face of one of theparallel sides of the frame by means of I have clamping-crews h,extended out through perforations in said sides and nuts ion the ends ofthe screws, as shown in Fig. 1.

J and J 2 are mating metal plates adapted tobe fixed on the ends ofatailings-board K. Each has an integral rack m and one end provided witha tongue 0, adapted to fit in the groove 0 of one of the metalboard-bearers,

and the other end portion tapered and per forated and adapted to overliea correspond ingly-tapered end of the boardK and to be fixed thereto bymeans of bolts and nuts, as required to produce a scarf-joint. p

N is a rotatable rod extended through the perforated lugs f. Pinions 0,fixed to the rod, engage the rack on. a crank-handle s are on one end ofthe rod, and a pawl y is pivoted to the plate A to engage theratchet-wheel.

By relaxing the force of the clamping-screws h the board-bearers Band Bcan be readily adjusted as required to change the angle of thetailings-board K, and by rotating the rod N the board can be readilyraised and lowered, to be retained at any elevation desired, by means ofthe pawl and ratchet, and it is obvious such adjustment can beadvantageously made while the machine is in operation.

A ratchet-wheel r and Having thus described the construction,ap-

plication, and operation of my invention, its practical utility will bereadily understood by persons familiar with the art to which itpertains, and

What I therefore claim as new, and desire to secure by Letters Patenttherefor,- is

1. A metal bearing for an adjustable tailings-board in a thresher,consisting of a metal casting having a straight groove extending fromtop to bottom, an integral curved and slotted arm extending laterally atone side of said groove and an integral perforated support for a shaftextending in the opposite direction from the other sideof the groove,flat plates adapted to be fixed to the end portion of a tailings-board,each having an integral rack extending vertically on its outside faceand an integral tongue extending from top to bottom at one end adaptedto enter said groove 10 end to enter a groove in one of the metalboard-bearers, a rod having fixed pinions to engage the racks, aratchet-wheel and crankhandle on the end of the rod and a pivoted pawlto engage the ratchet, arranged and combined to operate in the mannerset forth for I5 the purposes stated.
